Geology and geography
The Kohuora complex is a freshwater wetland found in a tuff ring, that has an explosion crater around 600 metres wide and 30 metres deep. Kohuora erupted an estimated 34 million years ago, and the irregular V-shape of the complex indicated that there were at least three explosion crater vents. Peat and lacustrine deposits layer on top of the volcanic soil of the Kohuora.The Kohuora wetland is an important habitat for native bird and plant species, including Carex subdola, a sedge rare in the Auckland area.
